I must remove (1) steam and (2) dust particles from flue gases. But there is too much pressure drop if I use multiple equipment for both (e.g. a steam condenser/ heat exchanger and cyclone/ ESP/ scrubber). I want something a cost-effective solution for this. Can a cyclone separator do the trick? Will steam condense in a cyclone and come out from the bottom along with dust particles? Has it been done before?
Some of the concerns I have are-
1. Can I introduce steam + dust in a cyclone separator?
2. If I try to recover heat from the steam by condensing it in a heat exchanger, where will the dust go? Will it come out of the exchanger, or will it accumulate in the shell side?
Note: Condensing steam is desirable here- I don't want it to be emitted through the chimney.
Steam in the vapor state will not separate from air in a cyclone or any other such device. You could condense the steam into tiny droplets and those would separate. If you have both steam and dust, you will get some sort of sludge, which is a challenge to work with, especially on a continuous basis. That's why we design systems that avoid this combination and why you readily don't find solutions on the Web. [Is this the same 700°C flue gas thing?]
Thanks, Dudley J Benton ! This is different from the flue gas stream at 700 deg C- much colder, and hence not planning to recover the energy from this one.
Magnetize the flu particles and then cross the flu inside the magnetic field.
